The Summit Viper you have a link to is definately a steel model. I had one just like it. It is a great stand butheavy. The newer aluminum models are much lighter and pack better. I do not know much about the Brutus stands but forabout the same you could get the Summit Bushmaster from Cabelas:

IMO this would be a better stand.
